RAILROAD'GRADE-CROSSING CONSTRUCTION. f

' l i Application filed March 2, 1925. Serial No. 12,608.

To all whom it may concern:

Be it known that I, CLEM DRENNoN, a citizen of the United States,residing at Edwardsville, in the county of Wyandotte Y utility ofdevices of this character. i

VVit-h these and other objects in view, th invention consists incertain'novel features of construction as hereinafter shown anddescribed and then specifically pointed out in the claims, and in thedrawings illustrative of the preferred embodiment of the invention-Figure 1 is a transverse section of the im# proved device together withthe side elevation of one of the ties and a pair of the rails intransverse section.

Figure 2 is a plan view of the parts shown in Figure 1. Y

Figure 3 is a sectional detail on the line The improved device isconstructed in three sections, an intermediate section supported on theties and between the rails, and lateral sections supported on the tieseX- ternally of the rails.

The intermediate section includes spaced supporting members 10,preferably of portion of I beams bolted or otherwise attached to theties between the rails, one of the ties being represented at 11 and therails at 12. Bearing upon the supports 10 is a metal plate 13 withdownturned side edges 14, the latter spaced from the confronting facesof the balls or treads of the rails 12.

The supports 10 are so proportioned that the upper surface of the plate13 is located below the upper lines of the treads of the rails 12. Theiange 14 is extended above the upper line of the plate 13, and even withthe upper lines of the balls or treads of the rails 12.

The upper portions of the supports 10, v

at the ends are cut away at an angle, as shown in Figure 3, and theadjacent portions of the plate 13 bent down over the cut away portionsas shown at 16 in Figure 3, to form inclined approaches to the bodypfthe plate from either direction, Stop strips 17 are attached to theouter parts of the inclined portions 16 of the plate 13, as shown inFigure 3.

Disposed upon the plate 13 and its inclined margins 16 is a layer ofasphalt or the like, and indicated at 18, the extensions 15 and thestrips 17 operating as stops to confine the asphalt in position andprevent-Y ing it from spreading.

Attached -to the lower outer faces of the fianges 14 are strips 19preferably of hard wood, and extending beneath the balls or treads ofthe rails 12, and operative to prevent foreign matter from passingbetween the rails and flanges.

The lateral portions of the improved device are alike so that thedescription of one will suffice for both, and consist ofy supportingmembers 20, preferably of I beams, and attached to the ties 11externally of the rails 12. Bearing upon the beams 2O are plates 21 withdownturned edges 22and 23.

The supports 2O are so proportioned that the upper surfaces of theplates 21 are located below the upper line of the balls or treads of therails 12, and attached to the outer faces of the turned down portions 22and 23 are stop strips 24 and 25, while like stop strips 26 aresupported at the ends of the plates 21, the strips operating to confinelthe asphalt covering 27.

The bearing surfaces 18 and 27 are in alinement with the upper lines ofthe treads of the rails 12, as shown, and present an even uniformsurface unbroken except for l ,A y l 1,550,519v

UNITED STATES the relatively narrow space between the flanges 14 and theballs or treads of the rails,

for the passage of the flanges of the car' tion of the ordinary asphaltpavement.'

With a device thus constructed, the crossing is no different from theroadway at each side of the crossing.

The preferred embodiment of the invention is disclosed in the drawingsand set forth in the specification, but it will be un derstood thatmodifications within the scope of the claimed invention may be made inthe construction without departing from the principle o'f the inventionor sacrificing any of its advantages.

Having thus described the invention, what is claimed as new is l. Agrade crossing comprising supports adapted to bear upon railway tiesadjacent to the rails, plates bearing upon the supports and withdownturned edges, stop ribs directed above said downturned edges andextending above the upper lines oit' the same, anda layer or'cementitious material dispose l on the plate and confined at the edgesby said ribs.

2. A grade crossing comprising supports adapted to bear upon railwayties adjacent to the rails, plates bearing upon the supports and withdownturned edges, stop ribs directed above said downturned edges andextending above the upper lines of the same,

a layer of cementitious material disposed on the plate and confined atthe edges by said ribs, and a guard strip attached to one downturnededge of each strip and extending beneath the tread of the rail.

3. A grade crossing comprising supports adapted to bear upon railwayties adjacent to the rails, plates bearing upon the supports and withdownturned edges, stop ribs directed above said downturned edges andextending above the upper lines of the same, a layer ot cementitiousmaterial disposed on the plate and' conlined at the edges by said ribs,a guard strip attached to one downturned edge ol' each rib and extendingbeneath the tread of the rail, and a strip of ,yieldable materialattached to the guard
